    GUI - controls

    Controls and communication

    Comm port

  • Select the communications port for the OSD
  • Baud Rate

  • The default baudrate is normally 115200
  • Use 57600 for Mavlink based systems such as Ardupilot/APM/PX4
  • Passthrough

  • If connecting through a supporting FC, enable this
  • Select the appropriate UART the OSD is connected to
  • FONT Tools

    Edit Font

  • Editor for currently loaded font file
  • Write Font

  • Uploads fontfile from the GUI into the OSD
  • Load Font

  • Browse for an alternative font file to load into the GUI
  • OSD Controls

    Read

  • Reads values from OSD into the GUI (including screen layouts)
  • Write

  • Updates the OSD with values set in the GUI (including screen layouts)
  • Default

  • Resets the board to OSD default settings
  • Restart

  • Restarts the OSD - sometimes required after saving changes

  • GUI - configuration options

    Voltage

  • Voltage source – select the source of voltage – from FC or direct to OSD
  • Auto Detect – Use battery cell count – this uses configured fixed cell count and alarm values for the battery state gauge and alarms.
  • Auto Detect – Autodetect cell count / alarm – this autodetects the number of cells and determines alarm voltage based upon the autodetect cell alarm voltage.
  • Voltage adjust - use this to adjust the displayed voltage to match the actual battery voltage. Note if voltage is taken from the flight controller this adjustment is not applicable.
  • Voltage alarm - if not using autodetect, set this to the voltage at which you require the battery voltage to start to flash.

    Amperage
  • Amperage – direct connect - select this for Amperage values from sensor connected directly to OSD.
  • Amperage – use FC - select this for Amperage values from FC.
  • Amperage – use virtual - select this to use a software estimation of calibrated current draw against throttle position.
  • Amps zero adjust - use this to set the correct idle / zero current draw displayed
  • Amps adjust - use this to set the correct current draw displayed at mid throttle
  • mAh Alarm - use this to set alarm warning for bat capacity. Zero is disabled
  • Amp Alarm - use this to set alarm warning for Current draw. Zero is disabled
  • !! NOTE !! - remember to select 5v reference if using direct Amperage
  • !! NOTE !! - see guide for how to calibrate

    RSSI
  • RSSI source – direct analog – use analogue voltage connected to OSD.
  • RSSI source – direct RSSI – use PWM RX signal connected to OSD.
  • RSSI source – from FC – use RSSI value from FC.
  • RSSI source – RC channel – use RX channel from FC.
  • RSSI channel – channel when using source = RC channel.
  • RSSI alarm - set this to the value at which you require the RSSI value to start to flash
  • Min - minimum value with TX turned off.
  • Max - maximum value with TX turned on.
  • !!NOTE !! - remember to select 5v reference if using direct analog RSSI
  • !! NOTE !! See guide for how to calibrate

    Display Callsign
  • Disabled - do not show callsign
  • Show permanently - always on when enabled in screen layout.
  • Display every 4 seconds every minute - when enabledin screen layout.

    Reference Voltage
  • You must select this if you wish to use > 4s
  • You must select this if you wish to use HW current sensor or Analogue RSSI
  • !!NOTE!! This requires a smooth power supply to the OSD when enabled

    Other
  • Video signal - select AUTODETECT, NTSC or PAL to match your Camera
  • Transmitter type – select transmitter channel ordering for APM/PX4/MAVLINK
  • Mavlink system id – must match id of FC. Default is 1
  • Test alarms – enable/disable prominent alalrm messages such as “Low Voltage”
  • Throttle display type - shows PWM throttle value or %
  • Vario indicator size – single character or multiple rows for increased resolution
  • Metric or Imperial for units of display and measurements
  • Transmitter reverse – channel reversing if needed for APM/PX4/MAVLINK
  • Battery Health icon - shows static or remaining capacity battery icon
  • Statistics – show statistics for full flight or since armed
  • Map mode – display aircraft, home or both positions as a map relative to launch
  • Analog sensor type – 1.1v is more accurate, but mandatory to use 5v for > 4s or if using direct analog RSSI or current sensors
  • Audio vario deadband – if not zero, creates an area of no sound around horizontal flight
  • Audio vario throttle switch – if throttle is above this value, audio vario is suppressed as under power. 1000 always off, 2000 always on

    GPS
  • Display type - enables masking of major GPS digits with false values. Replace these with co-ordinates of the area to find downed aircraft
  • Fixedwing BARO/ALT - enables use of BARO and MAG data instead of GPS. GPS is default and previously always used for OSD

    LAYOUT
  • OSD screen switch - choose to enable screen switching by FC OSD switch function (2 layouts) or RC channel (3 layouts)
  • RC channel – channel used for Screen switch if enabled

    HUD
  • Sidebar height – adjust height of HUD sidebars
  • Sidebar width – adjust separation of sidebars

    Alarms
  • Setting to 0 disables alarm
  • Distance Alarm - use this to set alarm warning for max distance
  • Altitude Alarm - use this to set alarm warning for max altitude
  • Speed Alarm - use this to set alarm warning for max speed
  • Timer Alarm - use this to set alarm warning for timer (in minutes)

    VTX
  • Adjust VTX values for supported FC


    GUI - configurable screen layouts

    Understanding the concept of how it works
  • This is significantly changed in R1.8 – elements are only enabled / disabled on the screen editor instead of additional menu options
  • 1, 2 or 3 layouts can be uploaded to OSD
  • FC using OSD switch functionality supports 2 layouts, RC channel supports 3
  • Use the layout editor to create a layout that is available to the OSD to use
  • Fields can be enabled or disabled per layout using the editor switches
  • Fields can be moved around by click / drag of the screen item
  • Middle mouse click on screen item selects the corresponding switch to enable/disable
  • Predefined layout templates can be used to help in creating your preferred layouts

    SAVE settings to file
  • Saves the settings to file for backup

    LOAD settings from file
  • Loads settings from a previously backed up file


    GUI - Elements

  • Efficiency - instantaneous Watts per kmh or mph
  • Avg Efficiency - mAh used per minute of flight time

    GUI - FC emulator

  • Use this to simulate a MSP class flight controller connected to your OSD (Betaflight, Cleanflight, iNav etc.)
  • Primarily used for OSD development

    Firmware Flasher

  • Easy and quick upload of pre-compiled firmware to OSD!
  • Select version, Hardware device, FC or OSD variant and aircraft type
  • Key release notes and information is displayed for reference
  • Load firmware form online repository
  • Click flash and watch the progress
  • Alternative option to flash from a local binary
  • View and install test releases when available

    OSD - accessing the built in OSD menu

    To access the inbuilt OSD menu, with the FC DISARMED:
  • THROTTLE MIDDLE
  • YAW RIGHT
  • PITCH FULL

    To navigate the OSD:
  • PITCH/ROLL sticks are used to navigate
  • YAW stick is used to adjust / change values

    OSD - accessing the built in FC menu

    Access to the inbuilt FC menu is supported for some FC such as betaflight and iNav. With the FC DISARMED:
  • THROTTLE MIDDLE
  • YAW LEFT
  • PITCH FULL

    To navigate the FC menus, stick settings defined by the FC are used

    OSD - additional configuration settings

    config.h
    Further settings are available in config.h due to :
  • memory constraints to leave enabled permanently
  • rarely used
  • not yet moved to the GUI

    def.h Advanced settings are available in def.h.
  • Primarily for developers
